Needling mechanism of single-spindle single-needle-area needling machine

Abstract

A needling mechanism of a single-spindle single-needle-area needling machine comprises a frame, a transmission shaft component, a needling part, first balancing mechanisms and second balancing mechanisms. The transmission shaft component comprises at least one crankshaft set. Each crankshaft set comprises a left connection shaft, a first balancing crankshaft, a needling driving crankshaft, a second balancing crankshaft and a right connection shaft. Projections, on a projective plane vertical to an axis of each left connection shaft, of the axis of the corresponding left connection shaft, a boss center line of the corresponding first balancing crankshaft, a boss center line of the corresponding second balancing crankshaft and a boss center line of the corresponding needling driving crankshaft locate at the center and three tops of an equilateral triangle. First rocker arms of the first balancing mechanisms are connected onto bosses of the first balancing crankshafts in a sleeved manner. Second rocker arms of the second balancing mechanisms are connected onto bosses of the second balancing crankshafts in a sleeved manner. Third rocker arms of lifting driving mechanisms are connected onto bosses of the needling driving crankshafts in a sleeved manner. The needling mechanism of the single-spindle single-needle-area needling machine has the advantages that stable running of the transmission shaft component can be kept during high-frequency needling, and vibration and shaking of the needling machine are reduced greatly.

Description

technical field [0001] The invention relates to an acupuncture machine, in particular to an acupuncture mechanism for a single-spindle and single-needle area acupuncture machine. Background technique [0002] In the existing single-spindle and single-needle zone acupuncture machines, the acupuncture mechanism generally includes a frame, a transmission shaft assembly and acupuncture parts. The transmission shaft assembly is rotatably mounted on the frame. The acupuncture parts are connected; the transmission shaft assembly includes a left half shaft, a right half shaft, and at least one crankshaft sequentially connected between the left half shaft and the right half shaft; the crankshaft includes two shaft heads and a boss integrally connected, The two shaft heads are respectively arranged on the left side and the right side of the boss, the axes of the two shaft heads coincide, the boss is cylindrical and its center line deviates from the axis of the shaft head; The axis co...

AI Technical Summary

Problems solved by technology

[0004] When the acupuncture machine is working, if the acupuncture frequency reaches more than 1200 times / min, due to the self-weight of the acupuncture components (needle plus the self-weight of the needle beam and needle plate), the drive shaft assembly will generate a strong inertial force during operation , so that the needle loom produces severe vibration and shaking, and at the same time generates a lot of noise

Acupuncture machines produce severe vibration and shaking during work, which will seriously affect the quality and output of acupuncture products, and even resonate with production plants and other equipment, causing major safety hazards
